PHP7 RC7 Release Comparison of PHP5.6 Quick Sort 20000 Data Performance Experience and New Syntax Tryout_PHP Tutorial

PHP7 RC7 Release compared to PHP5.6 quick sort 20000 data performance experience and new syntax tryout

Recently, Zend’s PHP7 has been in the final bug fixing stage, and RC7 has been updated. According to Zend’s official statement, the performance of PHP7 is about 2 times higher than that of the PHP5 series version, and some new syntax has been added. Some factors affecting performance of PHP5 have been removed, and the following Features have been mainly added.

• Improved performance: PHP 7 is up to twice as fast as PHP 5.6 Consistent 64-bit support 64-bit consistency support Many fatal errors are now Exceptions Remove of old and unsupported SAPIs and extensions Removed old unsupported SAPIS and some extensions The null coalescing operator (??) Combined comparison operator () Return Type Declarations are displayed the same as C language, etc. Return value type Scalar Type Declarations Scalar type definition Anonymous Classes Anonymous classes! Out of curiosity, I installed PHP5.5 and PHP7 RC7 Release at the same time to experience it, so I experienced the performance improvement and new syntax of PHP7 respectively. As for how to install and configure PHP7 I believe I don’t need to say anything else, no more nonsense.

  1. Performance comparison between PHP7 and PHP5.5 How much has the performance of PHP7 improved compared to PHP5.6? You will know by testing it with a simple and silly code. Here I will use the 5.5 version of PHP to compare. There is only 5.5 on the computer and I am too lazy to install PHP5.6.
  As shown below php7 and php5.5:
  
  

  1.1 Here I use a small piece of silly code to test PHP:

  <!--?php
  function microtime_float()
  {
  	list($usec, $sec) = explode( , microtime());
  	return ((float)$usec + (float)$sec);
  }
  define('ARRAY_SIZE',20000);
  function QuickSort($arr,$low,$high)
  {
   if($low-->$high)
     return ;
   $begin=$low;
   $end=$high ;
   $key=$arr[$begin];
   while($begin=$key)
  	   --$end ;
  	$arr[$begin]=$arr[$end];
  	while($begin<php7 rc7 release comparison of php5.6 quick sort data performance experience and new syntax tryout_php tutorialpre>

  After running 20,000 random data under PHP7 and PHP5.5 respectively, the result after the quick sort algorithm is that PHP7 is 12 times that of PHP5.5!!!! It seems that PHP7 is starting to take off! <br php7 rc7 release comparison of php5.6 quick sort data performance experience and new syntax tryout_php tutorial>

  <li class="level1"><code>declare(strict_types=1)该指令必须是第一个指令而且只有一种用法 <php7 rc7 release comparison of php5.6 quick sort data performance experience and new syntax tryout_php tutorialcode>The so-called concept of strict typing and strong typing is that we have to abandon the concept of type before PHP5.6, because we know that PHP itself is a typed language. Because of this, type conversion and type checking lead to the PHP language The extremely low performance of php7 also proves this point, for example, the following code
  <pre class="code">
  <!--?php
  declare(strict_types=1);
  function GetInt():int{
    return 1.0;
  }
  echo GetInt();

  If you change the above code to return 1;, it can run normally, otherwise an error will be reported. This is the strong type constraint of PHP7. In this mode, the if type is completely abandoned.
